The Joint Stock Company "B", which is dedicated to the marketing of cereals, has established in its statutes the fiscal year that coincides with the calendar year.

With the purpose of adjusting the financial year to the calendar of the cereal marketing campaigns, the General Shareholders' Meeting, validly constituted for this purpose, agrees on April 19, 2022 to modify the financial year of the entity, which will begin on June 1 of each year and will close on May 31 of the following year.

Consequently, on May 31, 2022 the current fiscal year closes (which had begun on the previous January 1), beginning on June 1, 2022 the first of the years adjusted to the modification agreed by the General Meeting.

In this case there are two taxation periods, both starting within the same calendar year of 2022 :

  1. From January 1, 2022 to May 31, 2022 .
  2. From June 1, 2022 to May 31, 2023 .

Therefore, Public Limited Company "B" will have to submit two Corporate Tax returns, one for each of the aforementioned tax periods.

2. Accrual

Regulation: Article 28 LIS

Corporate Tax accrues on the last day of the tax period.
